Izibani ze-neon zingamashubhu engilazi akhanyayo, akhanyayo noma ama-bulb agcwele ungqimba oluncane lwe-neon noma amanye amagesi angavamile; zingamalambu okukhipha igesi e-cathode ebandayo. Ishubhu le-neon ishubhu lengilazi elivalekile elinama-electrode emikhawulweni yomibili, egcwele{1}}igesi yokucindezela okuphansi. I-voltage yezinkulungwane ezimbalwa zama-volts isetshenziswa kuma-electrode, i-ionizing igesi epayipini futhi ibangele ukuthi ikhiphe ukukhanya. Umbala wokukhanya uncike kugesi eshubhu. Ukukhanya kwe-neon kuwukuhumusha kwesibani se-neon; I-neon gas, igesi eyivelakancane, ikhipha ukukhanya okuwolintshi okudumile-okubomvu, kodwa amanye amagesi akhiqiza imibala ehlukene, njenge-hydrogen (ebomvu), i-helium (epinki), i-carbon dioxide (emhlophe), kanye ne-mercury vapor (blue).
Izibani ze-Neon zingabahle bedolobha; njalo ebusuku, njengoba kuhwalala nezibani zikhanya, izibani ze-neon ezimibalabala zihlobisa idolobha ngobuhle obumangalisayo.
